Detecting An Element Overflow Condition

Aug 25, 2006

I'm building an application that lets a user enter a text string in a text input box, then I display the text string in a separate division using dynamic html techniques. I use innerHTML to rewrite a div, specifiying the style elements inside the <div> tag, and placing the text string between the <div> and </div> tags. I use the overflow:hidden attribute to keep the text from visibly overflowing.

However I'd like to be able to actually detect that an overflow has occured, so that I can truncate the text string (change the form input element value) so that it contains only the characters that 'fit' without overflowing the div element.

Is there a way to capture the event of a specific DIV element overflowing?

Detecting Text Overflow?

I have a width limited box on a website that contains text. Normally the text will break across several lines as expect just fine. However, every now and then there is a really long word that breaks out of the box:

Condition And Element.style...?

Aug 17, 2007

i am trying to have text-decoration applied on some text depending on the value of certain variable. If the value of myvar=0 text-deco =none and if it's 1 then text deco= line-trough...

Kind of the same thing that emails web apps like yahoo or gmail do with mails read or unread if it's unread then email title/subject is bold/strong but if it's read then email title is in normal font-weight...

here is some piece of code i have written to do that

the text on which i want to apply the conditionnal decoration is a table cell (cell2DisplayCell1), the text itself is inserted by the innerHTML instruction!

I tried to introduce the conditional statement with a function displaylinksLineThrough() which is defined in the second block code... Code:

IE7 Ignores 'overflow:hidden' When Moving Element

Dec 2, 2009

In the top right of the page is a JavaScript (Prototype) Carousel that scrolls through images when you click the arrows. It works properly in all browsers except IE 6 & 7 (it does work properly in IE 8) with my primary concern being IE 7. When you click on the right arrow to scroll to the next image it scrolls properly but the entire strip of images is displayed and it sites on top of the page's content.I've tried all of the overflow:hidden hacks I could find so.

Removinng Overflow-y Hidden/setting Overflow-y Visible?

Nov 12, 2010

I'm currently building a website that has a flash fullscreen popup at the beginning. The flash popup loads fullscreen, therefor I've set overflow-y to hidden. As soon as the flash popup is done, it removes the div it the flash is in using javascript, but I can't figure out how to put the overflow-y to visible.

I'm assuming I need to build a Javascript function to show overflow-y visible, and then need to call to that function from the flash file. I just can't figure out how to build the javascript function since I suck at javascript.

All the CSS is in the original file, so not in an external stylesheet, this needs to stay that way because I have to implement the code in to several different web sites.

Detecting When The Select Element's Dropdown List Is Open And/or Closed

Jul 20, 2005

I need to know when the select element's dropdown list is opened (as when the user clicks on the arrow or does ALT-downarrow from the keyboard). Similarly, I need to known when the dropdown list closes.

The closing of the dropdown list can happen without changing the dropdown, hence the onchange event is not a sure way to determine that the dropdown list closed.

Is this possible in Internet Explorer?

How Would I Discover The Text In A Block Element Hidden By Overflow:hidden Style Being Set?

Sep 20, 2005

Specifically, assume I have a div tag of absolute dimensions. I need
to figure out, first, whether or not the text inside the div tag is
partially hidden by the overflow setting, and if so, what the hidden
text is.

Is this even possible? Obviously, the rendering engine in the browser
"knows" this information, but is it accessible through Javascript?

Detect Overflow In A DIV?

Jan 24, 2009

how I might use JavaScript to detect the overflow of text in a DIV. Currently, I have the CSS set to Code:

overflow:auto

However, having scroll bars are pretty tacky. Instead, I'd like to be able to detect the overflow, which would then add a small <a href> link that says "More."

Stack Overflow In IE?

Mar 16, 2009

I discovered this really great jQuery plugin which adds a scroll to top link to every page (implemented through my CMS) - http://blog.ph-creative.com/post/jQu...ll-to-Top.aspxIn Firefox its fine but in IE after going through a few pages I start to get an alert box which says "Stack overflow at line: 13". I understand that this may be caused by an infinite loop but being a JS novice I'm kinda lost as to where to start.

Spill Overflow Text To Another DIV

Aug 8, 2005

Say I have a text area. When the user clicks a button the entered text
displays in a DIV. If there's too much text to fit in that DIV then the
overflow text (the text that doesn't fit in the first DIV) displays in
an adjacent DIV.

Is there a way to know if there's "overflowing" text and, if there is,
if there a way to know what that text is?

Height And Overflow: Auto;

Jun 8, 2006

Copy the following code and run it in IE and Firefox. In IE, you can see it works pretty damn good, with the center column using a div with "overflow". That is what I want!

Now, in Firefox, it doesn't work like that probably because it's doing it the RIGHT way

So, with that said, can any of you javascript guru's think of anything that we can use some JS to force the middle div to use that scrollbar when the content gets past the initial browser height? Code:

Is it possible to make a file insertion conditional? I now have the code:

If / Then / Else Help Needed - More Then One Condition Possible?

Sep 19, 2006

I want to write an if / then statement and have tried using this:

var MyVarMailto;
if (Request.Form("LoanRequest") == "Under $250,000") {
if (Request.Form("Organization") == "1") {
MyVarMailto = "emailA@address.com";
}
}
else if (Request.Form("LoanRequest") == "Over $250,000") {
if (Request.Form("Organization") == "1") {
MyVarMailto = "emailB@address.com";
}
}
else {
MyVarMailto = "emailC@address.com";
}

So basically I have a form that gets filled out and submitted which
passes the values to this page. I want to check the values against
conditions that you can probably figure out above and then set the
variable contigent to those values. I tried using AND after the first
condition but that doesn't do anything.

How To Add 1 Condition To Script.?

Nov 30, 2006

Currently have a txt input with default value="Your Name". with the on focus event to clear default text.

However if a user doesn't touch the txt box the the script goes on to validate the email box below because we have "Your Name" loaded up. and that passes validation below.

How do I go about adding another condition to look for string "Your Name" to the following if statement.

I tried adding another "||" statement after value.length <2 part and got nowhere.

function checkmailform(){
if ( (document.forms.newsletterform.Name.value == null) || (document.forms.newsletterform.Name.value.length < 2) ) {alert("Input First NewsName");
document.forms.newsletterform.Name.focus();
return false;
}else{...

Elseif Condition?

Apr 27, 2002

Is there a way in javascript to use multiple if conditions? For example I need something like this: Code:

if( email=="" )
{
do something
}
elseif( !issemail(email) )
{
do something else
}

I know it would be possible to use else and then another if but since this javascript code is PHP-generated and I'd have about 5 conditions, I can't really do this easily.
